To seal with epoxy or not?

Guys,
I'm not sure if i have to use epoxy sealer or not. I have been using SPI products epoxy/Turbo 2K primer and I will be using SPI base coat/clear coat.
Car is blocked and blocked and blocked again ( looks really good now, I was afraid at the beginning)but I got a few cut thru here and there to epoxy especially on ridges. Would base coat attack differently to epoxy then 2K so I would have problems? I will be spraying 4 coats SPI torch red/universal clear. I'm really tired and want to by-pass the sealer stage.
And How many ounce would be enough to spray one coat on a 67 camaro everything one shot?
Thanks in advance.

Skip it!
It would be only a problem if you piled the base over those spots without proper flash.

So why not spray a wet coat of base and walk away for 30 minutes. Let the first coat of base act as a sealer for you.

I love seeing your response Barry. It seems like all the big boy manufactures want to do is sell more product and would recommend sealer. I havn't used a sealer over totally primed parts in years. A quality urethane primer is the best base for color there is.

Start with 8oz than mix 8oz of urethane reducer. It will be close.

Barry, tisk tisk, come on now.

PT Camaro, you have a lot to learn, hang in there.
Let's start with some details. Are you talking about how much to buy? Or are you simply asking how much to mix up? Let me put it this way, you need to mix up all you will need to apply all the coats you are going to. If you come up short you just mix more. If you don't fill the cup (on the gun) up all the way, you will need to fill it more times. This doesn't have to be done in 12 and a half minutes with you moving 3.6 MPH. It is no be deal, relax, if you take hours painting this thing, it is no big deal. Mix some, paint some, mix a little more,it is no big deal. One thing is for sure, you need to paint a few things (the door jambs, SOMETHING) before you attempt a complete.

I thought it was a pretty good guess, on my part.

One spray-able quart of a solid color will do one coat of base on a Camaro.

Jambs and how he sprays will be another story of course.

Good starting point.

Can always mix more.

you should have laid epoxy primer down first, you can scuff epoxy and do some body work over it.as for 0ne sprayable quart, i doubt that is gonna make one coat.if your using b/c, you can thin your paint, and store it for a while if you dont use it all. better to have more, than not enuff. i would spray at least 4 -5 coats of color, then at lest 3-4 of clear,let it dry, wetsand and spray a flowcoat of clear,and cut and buff

I must be doing something wrong because it takes me about twice as much paint for one coat.

8oz plus 8oz makes 16oz. 16oz is a pint, a quart is 32oz.

Brien, I was under the impretion somehow that I have to mix just enough to spray a coat that's why I was asking. So I would get consistent color everywhere.

It depends on the product you are using. If you are spraying a product that uses a hardener of some kind, well then you have a "pot life" (the time the product is sprayable before it starts to cure and harden) to deal with. If it doesn't use a hardener like many base coat paints, you don't have that pot life hanging over your head.

If you know you are going to be painting that Camaro and you know that a quart will be pretty close the amount you will need to get a coat on, mix a few quarts and spray. After the first coat you will know exactly how much it takes. If you have a whole quart left, spray the second coat and then mix up another for the last coat. If you have only a half of a quart, you know you can mix up one more quart and have enough to make it around the car again.Then make up a quart and a half and do the last coat.

After you spray the first coat, you will know.

As far as the color, I am not with you. If you have the paint in the can and you stir it up well each time you pour off from the can, the last time will be the same color as the first.

To do the outside of an average car it usually takes me somewhere between a quart to a quart 1/2 mixed, but base seems to go a little farther for me then clear unless a lot of mist coating is done. If the base is activated, then pay attention to how much you used on your first coat for a guide to how much you are going to need each coat and mix up enough for one complete coat at a time and keep doing it till everything is covered. If it isn't activated then don't worry about it, it will keep. When it comes to clear pay attention to how much you use on your first coat, and for your final coat mix that amount and a little bit extra for makeing sure you have a nice glossy wet coat, and to hit any areas where it may be a little dry with more clear before it sets up. On the last coat of clear look down the panels from the side as you go along and if you see any spot that may be a little dry hit it with more clear before going to your next panel, but don't overdo it that you get a run. Some clears you have to be carefull with also, some like to flow out a little it seems after you are done spraying. I haven't used spi so can't tell you anything specific about that, but many others here have used it.
